The first thing is the basics, that is, the basic concepts should be familiar, which is the most important thing!

Then practice and do what you know.

Then there is the expansion exercise, trying to start from the basic knowledge points and think about the problem with other knowledge points.

For example: x? +2x-3=0, which can be solved by formula or simplified by x? +2x+ 1-4=0→(x+ 1)？ =4，x= 1

Compared with the formula method directly, it is much simpler. Of course, the example I gave is also very simple (⊙⊙⊙ B Khan)

I just want to say that there is more than one way to solve the problem. Time is not urgent. There's no need to dwell on this. Think more about whether we can solve it in other ways.

→ Well, for example, the coordinate method in solid geometry is the same as the geometric method, which is difficult here and simple there.

When you are in class and listening to the teacher, you will occasionally encounter some boring problem-solving methods, so simple that you have no friends, so write them down! Use a pen! Occasionally, if you encounter problems, you may discover a new continent.

You'll be familiar with math if you watch it too much. The important thing is to think alone. Don't look at the answer at once, or you will be taught a lesson. Let others give you a hint, and then keep trying. Finally, you can't ask anyone else. The process of independent thinking is very important, which will allow you to consolidate and sort out the knowledge points when thinking.

My former teacher taught me this. Although it will be a little pitted, the effect is not bad.
